If real countries are detailed in the plan, the public might mistakenly believe the plans are real. Using zombies gets around that problem (for most citizens, at least).
Using zombies was also fun, the report's authors write. By allowing the trainees' imaginations to run wild, the instructors were able to teach them about the basics of writing military plans and orders, they wrote.
"If you suspend reality for a few minutes, this type of training scenario can actually take a very dry, monotonous topic and turn it into something rather enjoyable," they wrote in a disclaimer to the report.

Also claims there are 8 types of zombies:
1. Pathogenic zombies are created by infectious agents
2. Radiation zombies
3. Evil magic zombies (EMZ) are the result of "occult experimentation." I'd put voodoo zombies in with this crowd even though the state usually chemically induced (drank some zombie juice)
4. Space zombies come from space or originate from extraterrestrial toxins/radiation
5. Weaponized zombies are bioengineered by hostile forces (the Resident Evil kind)
6. Symbiant-induced zombies are similar to pathogen-induced zombies, but they are created by parasitic life forms and don't kill their host right away (like zombie ants or phorid fly).
7. Vegetarian zombies (destroy crops)
8. Chicken zombies - which are real, sort of.

If people are willing to dig down 6ft & bust open a concrete cask just to break open a casket, I seriously doubt iron bars would stop them. Especially these days with tools like blow torches & cordless sawzalls readily available.

Only $113,000 for the kit, options extra.
But, to get your money back...

Please note -- we require medical evidence of the presence of a real zombie should you wish to claim under the 10 year anti zombie guarantee

Should the zombie apocalypse ever hit, I seriously doubt anyone will be that concerned with getting their money back (until it's over) or that anyone will be answering phones to process your refund (even after it's over).
